Dragon 32 PSU internal photos?

Post by Vee »

Hi all,

I'm trying to repair a Dragon 32 PSU. The output voltages are a bit wonky, as in no 28V AC.
I've drilled the rivets out to check the transformer coils at intact and while the output coils seem to line up with the diagram I found, the input coil does not.
There are three tags across the bottom and one at the top. The earth goes to the top tag, the live to bottom left and neutral to the bottom right.
But there's no continuity across the L-N tags? There is however continuity from the live to the center tag.

I can only assume the transformer is toast, or has someone been inside this PSU before me? Or have I missed something obvious?

Any help greatly appreciated.

Hi,

We have some pictures of the internals of at least one PSU model, which you can see here.

Can you post some pictures of yours?

Cheers,
Rob
